Abstract

The cell for integration into a room of a building is assembled of several cell elements provided on their peripheries with profiles which are constituted so that they engage with the corresponding profiles of the adjacent cell elements.

Description

The invention relates to a room cell for installation in a room of a building comprising a plurality of elements, which are composable to the room cell.

In general, space cells are known, which consist of a frame to which side walls, roof panels and floor panels are attached. Such prefabricated space cells allow the prefabrication of individual elements and the rapid assembly of these elements to a room cell.

Furthermore, room cells are known in which complete rooms, especially complete bathrooms and toilets, are prefabricated in the room cell, and then this completely prefabricated room cell is then used for example in a building. The main body of such a space cell is made for example of reinforced concrete and is removed from the construction site inside and preferably fully equipped. However, such space cells can only be used in new buildings, since only there during suitable construction stages, the insertion of such a complete room cell in the partially completed structure is possible. In a refurbishment or a finished shell of a building, the insertion of such a room cell is not possible because the space to install the completely manufactured room cell not more is given and sufficiently large building openings are no longer available.

However, it is desirable that even with a room cell for installation in a room of a building on the one hand, all elements of the room cell can be prefabricated and a faster and easier construction of the room cell in place in the space of the building is possible and on the other hand, a high degree of flexibility in the selection of materials according to customer requirements and space requirement is present.

The object of the invention is to provide a room cell for installation in a room of a building, which is easy and inexpensive to produce for different requirements of the room cell.

This object is achieved by a room cell having the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Due to the fact that the space cell according to claim 1 comprises several elements that can be combined to form a room cell in the relevant room of the building, it is possible to incorporate the room cell in rooms of a building which, compared to the size of the room cell, have a very small building opening, for example, a door opening, have. Each of these elements has on each of its sides a profile which can serve as a means of attachment to other elements. The profiles of adjacent sides of two elements are formed such that a first profile of a first element engages in an adjacent second profile of a second element. As a result, a simple assembly of the space cell according to the invention in a simple manner possible. The engagement allows a positive connection between the two elements. As a result, two elements of the space cell can be relatively firmly connected together in a simple manner. The profiles are provided on each side of each element, which, by means of the profiles, makes all adjoining sides more adjacent Elements can be connected to each other. As a result, a closed room cell can be easily installed in a room of a building.

FIG. 1 shows a side view of a wall element 10 of a room cell according to the invention from the outside of the room cell. The element 10 adjoins laterally to further wall elements 12 and 14 and at the bottom to a bottom element 16 and at the top to a ceiling element 18. The connection between profiles of the element 10 and the wall elements 12, 14 will be described in connection with Figure 4, the compound of a profile of Elements 10 with the bottom profile 16 in connection with Figure 13 and the connection of a profile of the element 10 with the ceiling profile 18 in connection with Figure 16 explained in more detail. The element 10 comprises a filling element 20, for example a cement fiber board. With this filling element 20 is at the top of a profile 21, on the left side edge of a profile 22, at the bottom of a profile 24 and at the right edge a profile 26 is provided which are firmly screwed to the fiber cement board and / or glued. Of the wall element 10 adjacent to the element 12 is connected to the profile 22 profile 26, of which is connected to the wall element 10 bottom element 16 is the profile 28, of which the wall element 10 laterally adjacent wall element 14 is the profile 30 and of the On the wall element 10 adjacent ceiling element 18, the profile 32 in Figure 1 is visible. The profiles 21, 22, 24, 25 each have a C-shaped groove 34, 36, 38, 40, can be used in the screws.

Preferably, in these C-shaped grooves 34 to 40 screws with T-shaped basic shape can be used in a suitable size, which are inserted through the opening of the C-shaped profile in this and locked by turning the rectangular head in the profile. Such screws are for example so-called hammerhead bolts, especially Halfenschrauben. This makes a very simple insertion and alignment of a screw in the profile possible. With the help of such screws stiffening elements 42, 44, 46, 48 are connected to each other with one end of adjacent profiles of the element 10 together. By these stiffening elements 42 to 48, the angle between two adjacent profiles is fixed and the adjacent ends of the profiles 21, 22, 24, 25 connected to each other. As a result, a profile frame of the element 10 is formed. Other connection options for profiles 21, 22, 24, 25 are possible. For example, the ends of adjacent profiles 21, 22, 24, 25 can be welded or plugged together. Also, recessed joints between the adjacent profile ends are advantageously used. The profiles can be, for example, continuous casting profiles, in particular extruded aluminum profiles, multi-folded lightweight steel profiles or plastic profiles.

The interlocking connection between the profile 22 of the wall element 10 and the profile 26 of the wall element 12 and between the profile 30 of the wall element 14 and the profile 25 of the wall element 10 is secured in an interlocking state of the respective profiles by means of a locking arrangement 50, that a release of the interlocking profiles 22/26; 25/30 is no longer possible. By means of arranged in the groove 36 of the profile 22 and in the groove 40 of the profile 25 guide pin 52, 54 and provided in the locking arrangement 50 slots 56, 58, the position and the possibility of movement of the locking assembly 50 is fixed. Alternatively and additionally, a second locking element 60 is provided for locking the connection of the profile 30 with the profile 25, which includes two obliquely arranged to the longitudinal axis of the locking element 60 slots 62, 64. Further, 25 two further stud bolts are arranged in the groove 40 of the profile, is guided by the movement of the locking element 60 in the horizontal and vertical directions. In the illustrated in Figure 1 positions of the locking elements 50 and 60, the locking of the mutually engaged profiles 25 and 30 is not yet done.

Only after a movement of the locking arrangement 50 in the direction of the arrow P1 or after a movement of the locking element 60 in the direction of the arrow P2 and the profile 30 is at least partially covered by the locking assemblies 50, 60 and thereby can no longer leave the position in the it is engaged with the profile 25 of the element 10. The stud bolts 52, 54, 66, 68 may alternatively also include a head whose dimensions are greater than the width of the elongated holes 62, 64. As a result, the locking elements can be captively connected to the element 10 at least in one position. Preferably, at least one stud bolt has a rectangular head whose longitudinal side is arranged approximately transversely to the longitudinal extent of the slot 62, 64.

FIG. 2 shows a cross section of the profile 26 connected to the element 12. FIG. 3 shows the profile 22 of the element 10, which engages in the profile 26 shown in FIG.

4, the profiles 26 and 22 are shown in a nested state with the aid of a sectional view in which parts of the profile 26 engage in areas of the profile 22. As already described in connection with FIG. 1, the profile 22 is connected to the filling element 20. The filling element 20 is preferably glued to the profile 22. Additionally or alternatively, the filling element 20 may be screwed to the profile. A filling element 66 is connected to the profile 26. In the assembled state of the profiles 22 and 26, the filling elements 66, 20 are arranged such that they form an inner corner of the space cell 72. On the inside of the filling elements 20 and 66, ie on the side of the filling element directed towards the interior of the room cell, tiles 69, 70 are adhesively bonded, which form the inner surface of the elements 10 and 12 and thus the inner surface of the spatial cell indicated by 72 in FIG form. The sectional view shown in Figure 4 corresponds to the cross section along the section line BB of Figure 1. The cross section along the section line AA of Figure 1 is then a mirrored on a vertical axis representation of the representation shown in Figure 4.

FIG. 5 shows a cross-section of a section of the element 10 along the sectional plane E-E according to FIG. 1, with only the profiles 25, 30, the stud bolt 68 and the oblong hole 64 being shown. When a force is applied to the locking element 60 in the direction of the arrow P3 according to FIG. 1, the locking element 60 is simultaneously moved in the direction of the arrow P4 shown in FIG. 5 according to FIG. As a result, the top of the profile 25 is covered by the locking element 62, so that the standing in engagement with the profile 30 profile 25 can no longer escape from this engaged position. The locking element 60 then has the position 60a. The guide pin 68 is formed for example by a Halfenschraube and is held by means of a plane parallel to the element 10, so that the locking member 60 in Figure 5 can not be pushed away in the direction of arrow P5. Such a securing of the locking element 60 may e.g. with the help of a screw, so-called snap rings, a split pin or other suitable aid done. In order to avoid a displacement of the elements 10 and 14, only a small clearance between the locking element and the profiles 30, 25 is allowed, so that between the locking element 60 and at least the profile 25 a non-positive connection is generated. FIG. 6 shows a top view of the locking element 60 and FIG. 7 shows a side view of the locking element 60. The locking element 60 is at least in the region between the locking pins 66, 68 formed such that it rests flat on the profiles 25, 30.

The profile 104 is connected to a filling element 108 and the profile 106 to a filling element 110. On the inside of the room cell facing surface of the filling elements 108, 110 is a respective marble layer 112, 114 glued, which then forms the inner surface of the room cell. In FIG. 20, a profile 116 and in FIG. 21 a profile 118 are shown, each of which has mutually complementary engagement elements 120, 122. The profiles 116, 118 each have a portion 124, 126 which is angled at approximately 45 ° to the longitudinal axis of the respective profile 116, 118, the mutually facing surfaces in the assembled state of the elements connected to the profiles 116, 118 contact each other surface.

In Figure 22, the profiles 116, 118 in the assembled state, each with a filling element 125, 127 are shown. With the help of the profiles 116, 118 an inner corner 128 of the space cell 72 is formed, which has a high stability in the assembled state. Also in the connection of the profiles 116, 118 may be provided similar to the locking device 60 of Figure 1, a locking device to prevent unwanted loosening of the engaged profiles 116, 118.

FIG. 23 shows a longitudinal section through an element 130, which is similarly designed as a wall element like the element 10 according to FIG. 1. The element 130 has a gypsum plaster board constructed as a two-layer filling element 132, which has an upper transverse profile 134 and a lower transverse profile 136 appropriate manner is connected. In an upper groove 138 of the profile 134, the profile 32 of the ceiling element 18 engages. In a lower groove 140 of the profile 136 engages in two parallel projections 142, 146 of a profile 148, which is provided as an alternative to the profile 96 on the bottom element 16.

The profiles 136, 134 have the same cross-section and are arranged mirror-inverted to one another in the arrangement in FIG.

In Figure 24, two further elements 150, 152 are shown, each containing at its edge a profile 154, 156, which have the same cross-section as the profiles 134, 136. A formed on the profile 154 projection 158 engages in an opening 160 of Profile 156, whereby the profiles 154, 156 are fixed to each other. The profiles 154, 156 have the same cross section, whereby the number of different profile shapes for the construction of a space cell according to the invention can be reduced. Furthermore, the profiles 136, 138, 154, 156 have a relatively rectangular or square cross-section, whereby these profiles have a relatively high stability under connection stiffness. Further, in the C-shaped grooves of the profiles 134, 136, 154, 156 further fastening means can be introduced, which can then be used for example for anchoring the room cell with the building.

FIG. 25 is a sectional view of the cross-section of a profile 170 with three openings 172a, 172b and 172c, each offset by 90 ° on three sides of the profile 170 and each forming a C-shaped groove.

Referring now to Figure 26, there is shown a cross-sectional view of the profile 174 having two opposing apertures 175a and 175b and a projecting hook-shaped engagement member 176 for engaging one of the apertures 172a-172c of the profile 170. With the aid of the profiles 170 and 174, a corner connection between two wall elements and / or between a wall element and a floor or ceiling element can be produced in the same way, as with the help of the profiles 154, 156 of Figure 24. In particular, the opening 172b of the profile 170 is similar to opening 160 of profile 156 and engaging element 176 of profile 174 corresponds to engagement element 158 of profile 154. As shown in FIG be used. Thus, for producing the connection shown in FIG between two adjacent elements 150, 152 also two profiles 174 are used, which have two opposite openings 175a, 175b and a projection 176 for engagement in one of the openings 175a, 175b of the adjacent element. A connection between two wall elements with the aid of the profiles 170, 174 is explained in more detail below in connection with FIG.

FIG. 27 illustrates the cross-section of a profile 178 which serves as a connection profile of a floor element or a ceiling element for connecting the floor element or ceiling element to a profile 170 or 174 of an adjacent wall element. The profile 178 can be used advantageously as an alternative to the element 90 according to FIGS. 12 and 13 and alternatively to the profile 32 according to FIGS. 15 and 16. The connection of a floor element and an adjacent wall element to form an inner corner of the room cell with the aid of the profile 178 is shown in FIG. 29 and will be explained in more detail in connection with FIG. The connection of a ceiling element with the edge profile 170 of an adjacent wall element to form an inner corner of the space cell is shown in FIG. 30 and will be explained in more detail below.

When using the profile 178 as a bottom profile whose underside serves as a wide support surface. The upper side of the lateral limbs 179a, 179b of the profile 178 serve as a support surface for an edge profile 170 of an adjacent wall element which is placed on the profile 178 from above. The profile 178 has two upwardly projecting webs 180a, 180b which, when joining the profile 178 to the adjacent edge profile 170, engage the opening 172b, whereby the profiles 178 and 170 are formed by a groove formed by the webs 180a, 180b and the opening 172b Spring connection are interconnected. When using the profile 178 as an edge profile of a ceiling element, the profile 178 is connected to the ceiling element such that the webs 180a, 180b of the profile 178 project substantially vertically downwards, so that they are pushed into the opening 172b of the edge profile 170 of an adjacent wall element and, as already described, form a tongue and groove connection. The profile 178 is provided on the floor element as well as on the ceiling element preferably circumferentially or at least in a partial area of each side of the room cell, so that with the help of the floor element or the floor elements and the ceiling element or the ceiling elements both at the bottom and at the top the space cell is a disk-like connection and fixation of the wall elements of the room cell.

FIG. 28 shows a ceiling profile 182, on the underside of which two webs 184a, 184b arranged parallel to one another protrude vertically downwards, an opening 186 being provided on the upper side of the ceiling profile 182 opposite the webs 184a, 184b, into which further profiles or connecting elements can be used. The downwardly projecting webs 184a, 184b are adapted to engage from above into the opening 172b of the border profile 170 of an adjacent wall element represented by dashed lines. The profile 182 has a contact area 188, with which a filling element of the ceiling element, such as e.g. a cement fiber board, a gypsum fiber board, a plasterboard or a plastic plate can be inserted and connected. The connection between the profile 170 and the filling element can, as already mentioned, take place with the aid of an adhesive, screwed and / or riveted connection.

FIG. 29 shows a sectional view of a vertical section of the inner corner between a floor element 198 and a wall element 200 of the arrangement of the room cell in a building in the assembled state. On the surface of the raw ceiling 190, a compensation layer 192 is applied, which is used in particular for leveling and for leveling the bearing surfaces for the space cell to be calculated. On this compensating layer 192, a layer 194 of an elastic plastic is arranged, through which the force acting downwards from a hollow profile 202 arranged on the layer 194 is uniformly introduced into the compensating layer 192. The layer 194 is preferably made of a Sylomer having a thickness of preferably 12 mm and thus forms a Sylomerlager. That on the Layer 194 resting hollow section 202 is connected to other hollow sections and forms a ladder or lattice-shaped base frame of the room cell. Of the other hollow sections connected to the hollow section 202, the hollow section 204 is shown in FIG. On the upper side at the outer lateral edge of the hollow profile 202, the profile 178 is arranged. The bottom element 198 of the space cell is formed by a honeycomb plate 206 resting on the base frame formed from the hollow sections 202, 204 and a light marble layer 208 arranged on this honeycomb plate 206. The honeycomb panel 206 rests on the upper side of the hollow profile 202 on its inner edge and is connected thereto to form a bottom element 198. The honeycomb panel 206 does not touch the profile 178 resting on the hollow profile 202 in the present exemplary embodiment. Between the honeycomb panel 206 and the light marble layer 208, an adhesive layer is disposed connecting the light marble layer 208 to the honeycomb panel 206.

Both the light marble layer 208 and the intermediate adhesive layer are not guided to the outer edge of the honeycomb plate 206, but ends before the edge of the honeycomb plate 206. Preferably, a step between the surface of the light marble layer 208 and the honeycomb plate 206 in the edge region of the honeycomb plate 206th formed, for example, has a width of about 1 cm. In this edge region, a rubber band 210 is bonded to the honeycomb panel 206 and / or the light marble layer 208, which serves as a rubber seal between the bottom member 198 formed of the honeycomb panel 206 and the light marble layer 208 and the adjacent wall member 200. In each case a profile 178 is preferably arranged on at least two sides of the room cell on the bottom element 198. Preferably, the profile 178 is arranged on the bottom of the room cell circumferentially on a circumferential hollow profile frame.

The edge profile 170 of the adjacent wall element 200 is connected to a wall plate 212 serving as a filling element. The outside and the back of the wall plate 212 and the inward side of the profile 170 form a common contact surface 214, wherein the profile 170 and the Wall plate 212 are connected to each other in particular by means of an adhesive and / or screw. On the inside of the wall plate 212, a light marble layer 216 is arranged. In particular, the light marble layer 216 is adhered to the inside of the wall plate 212.

The dimensions of the wall plate 212 are selected such that the wall plate 212 at least slightly compresses the rubber band 210 serving as a rubber seal, so that a sealing connection between the bottom element 198 and the wall element 200 is produced. After assembly of the space cell, the area between the light marble layer 208 and the bottom plate and the light marble layer 216 of the wall element 200 is filled with a permanently elastic material, in particular silicone, whereby this intermediate area is filled and sealed. For thermal insulation, a heat-insulating layer 218 is provided on the outside of the wall plate 212 between the wall elements 170 delimiting the wall element 200. This thermal barrier coating 218 may be e.g. with the help of rock wool or with the help of on the inside of the wall member 112 after joining the wall plate 212 with the edge profiles 170 by means of Ortschaum poured into the frame formed by the edge profiles 170 or sprayed onto the inside of the wall plate 212.

A room cell according to the invention preferably comprises a bottom part, a plurality of wall parts and at least one ceiling part. These components, which are also referred to as element according to the invention, are interconnected by means of profiles. Such a space cell is preferably used to install a wet cell, for example a bath or a toilet, in an already completed building shell. The filling elements of the wall, floor and ceiling panels are preferably lightweight panels such as e.g. Cement fiber boards or plasterboard. Preferably, these lightweight panels are moisture insensitive.

As filling elements, for example, so-called Wedi plates can be used, which have a core of extruded polystyrene foam and both sides a Glasfasergewebeamierung and a coating of plastic-coated mortar. Alternatively or additionally, two cement-bonded construction panels, such as the Aqua-Paneel brand, or mineral-bonded flat-pressed panels, such as the COSPAN / COSPANEL brand, can be used. Furthermore, plasterboard, gypsum fiber boards and / or wood-based panels can be used as filling elements. Also construction panels foams based on a synthetic rubber or elastomer with a self-adhesive coating, can be used alone or in combination with other filler material for the production of wall-floor and / or ceiling elements (in general elements). The elements can already be provided with a covering during production, for example in a production plant, on the later inner side of the room cell 72. Alternatively, these elements may also be provided with a coating on both sides, ie towards the inside of the room cell and towards the outside of the room cell. This is particularly advantageous if the outside is visible after the completion of the building.
